Application filed July 2, 1889. Serial No. 318,311.

To all tvhom it may concern Be it known that I, WILLIAM S. GUBEL- MANN, a citizen of the United States, re-

siding at Rochester, in the county of Monroe and State of New York, have invented new and useful Improvements in Calculating- Machines, of which the following is a speciiication.

' This invention relates to that class of .cal-

culating machines which are provided with a series of registering wheels and in which the registering wheels are actuated by key levers.

The object of my invention is to produce a machine of this character whereby the uprious operations of adding, subtracting,

multiplying, and dividing are mechanically performed in a simple and expeditious maning removed. Fig. 2 is a horizontal section toward the rear.

cross section of the rear portion of the machine in'line '55, Fig. 3 looking from the ner.

The invention consists of the improve- -mentswhioh will be hereinafter fully set forth and pointed out in the claims.

"In the "accompanying drawings consisting of six sheets, Figure 1 is a front elevation ofmy improved .calculating machine showing a number of transverse stop bars broken away and the indicating dials and dial casin line 22, Fig. 1. Fig. 3 is a longitudinal sectional elevation. Fig. 4 is a fragmentary cross section of the lower portion of the machine partly in line 44, Fig. 3, looking Fig. 5is a fragmentary rear. Fig. 6 is a fragmentary longitudinal .seotional elevation of the registering mechanism and connecting parts in line 66,

Fig. l, on an enlarged scale, showing the dials, movable sight plate, and dial casing attached. Fig. 7 is a fragmentaryltrans verse section in line 7 7 7, Fig. 6,"showin'g the dial casing and sight plate removed. v Fig. 8 is a fragmentary transverse section be the dial casing, dials, and connecting parts.

Fig. 9 is a top plan view of the same, Fig.-

10 is a fragmentary longitudinal se'ctional elevation similar to Fig, 6, showing the mechanism whereby the movement of one registering wheel is transmitted to'the next higher wheel, in a locked position; ii

is a similar view showingthe transmitting mechanism in an unlocked position.

Like letters of reference refer to like parts in the several figures.

A A represent'the side frames of the .ma-

chine which are connected at their front ends by an end frame a and at their cross bars a.

.B see Figs. 1, 3, 6, and '21 represents a series of registering wheels arranged. side by side in the upper portion of the machine 7 Patented N v. 9, 1915.

rear ends by and mounted upon a transverse shaft 2'; so

as to rotate independently of each other. The shaft 6 is held against turning by disks C Fig. 3 secured to the side frames A A. The wheels B are held-against retrograde movement by detents b suspended from a cross bar 6 secured between the disks G.

0 represents a gear rim secured to one 'side of each registering'wheel B. Each regis tering wheel B is preferably provided with one hundred teeth, and its gear rim 0 is also provided with the same number of teeth.

'0 represents a cam disk secured to the opposite side of each registering wheel B and each provided with ten abrupt inclines or' cams 0 there being one cam or incline c for every ten teeth on the registering wheel.

0 represents gear pinions one of which engages with the gear rim 0 of each registering wheel B.

The gear pinions c are each provided edials D arinclosed in a casing d arranged -Iaho've =1the registering wheels between the side-frames A- A. V flgiEach dial is providedlo'n' its upper face, nearits periphery, with two annular rows i of figures or numerals ranging from 'to 9 one row being arranged within the other an having the value of its'numerals increasing in a direction opposite to those of the other d? formed in the upper ends of the casing d and provided with as many sight openings d as there are dials D.

d represents a thumb piece formed on'the outer end of the sight plate D whereby the latter can be shifted.

(i represents 'a spring detent which engages against one of two notches d d on the top of the plate D whereby the latter is moved outwardly; so thatiwhen the plate is held in position to expose either the numbers in the outer row of the dials, or the numbers of the inner row of the dials. The sight openings 03 are of the proper size and so arranged as to expose only one of the outer figures on each dial when the plate is moved inwardly, and only one of the figures on the-inner row of each dial when the plate is inits first mentioned position, the figures exposed to view will increase in value from 0 to 9 as the dials are rotated, and when the plate is in the last mentioned position, the exposed figures will decrease in value forward movement, whereby the'wheel B is from 9 to 0, as the dials are rotated.

E represents a yoke or U-shaped framemounted on the cross bar 5 between each pair of detents b, As shown in Figs. '6 and each frame E consists of a forwardly and downwardly projecting cam finger e, a forwardly projecting pawl carrying arm e having a pawl e and a connecting sleeve 6 Thecam finger e is arranged to engage. with cam finger e is moved inwardly wvhen re-' the cam disk 0 of one of 'the registering wheels B, and the pawl arm and the pawl e 'to engage with the teeth the adjacent or next succeeding registering wheel.

6 represents a wlre springwhereby the leased from one of the cams. Thespring ve surrounds thegsleeve e and bears'with one end against the cam finger e and its opposite tooth of the .wheel B which indicates zero end against thecross bar 0. I

E represents a curved arm formlng'a rearwardly continuation of the cam finger e and carrying at its free end a friction roller E. This arm is so arranged with reference to the finger ethat" when, the latter is raised, or moved outwardly, the finger E will be moved inwardly, in front of the inclined advancing face of a succeeding cam 0 This mam construction compels the cam finger dc to move inwardly when released from thecam,

and assists the spring e in actuating the cam a wheel (Figs. 6, 7, 10, and 11) and also serving as a pivot for the pawl 6 e represents a similar pin secured to the free end of the pawl e and which rides over the advancing inclined face ofone of the teeth of the adjacent registering wheel so as .to engage against the abrupt 'back of the.

next succeeding tooth, when the arm 6' is elevated by the cam fingerv c as shown in Fig. 6, and which moves said wheel the distance of one tooth each time the cam finger is released and depressed by the spring e.-

e wheel B is ro--.. v

secured to the free 1 The range of-movement of the arm 6' is just suflicient to cause tlfe pawl to move the wheel B but one tooth at a time. The movement of the arm e. is such that the speed of the forward movement of the pawl will decrease as the arm and pawl assumea straight line as shown in Fig. 10. The possibility of im- I partinga movement-to the wheel B, sulficient to cause it to move more than one tooth at a time is thus practically avoided; but as an additional safeguard I permit the arm 6" todescend sufiiciently, momentarily, to cause the pin eito strike against the inc'lined advancing face of, one of the jteeth of the registering wheel B at'the same time that the pawl c has reached the limit of its practically locked against further rotation. At the same moment that the pin 6 engages between the teeth of wheel B, as shown in Fig. 10, the rear arm E strikes againsta. recoil spring 6, secured to the rearside of the cross bar 0 and deflects the spring sufficiently to allow the pin 6". of the arm-e to strike against the front side of one-of the advancing teeth of the wheel B and thereby retard its further movement. This engagement of the pin is but momentary as the re action of the spring 6" moves the arm E;

cam finger e, and pawl. arm 6' to the posi tion shown in Fig. 11, in which position the pin e clears the teeth of the wheel B.

The termination or highest point of each cam is arranged in a radial line with the onthedial D, so that inmoving the wheel B a distance of one tooth when its dial indicates 9, the cam finger 6, will drop or zontally side by side in the lower portion of the machine, and provided at their front ends with the usual keys f. The latter are numbered 1,2, 3, 4, 5, 6, 7, 8, and 9, respectively. The zero or key is arranged at the left hand side of the machine as shown at W, Figs. 1 and 2. Each.key lever is supported near its front end by a light spring and bears with its rear end against the lower curved side of a cross bar 9 secured to the rear end of a U-shaped carriage frame Gr. The side arms G of the latter are arranged on opposite sides of the key levers F and are pivoted at their front ends at g to the inner side of the side frames A A, and rest with their rear ends upon stops or pins 9 H represents a transversely and vertically movable slide or carriage, moving on guides or ways it h which latter are arranged one alcove the other and are secured at their ends to the side bars G of the frame G.

H represents a horizontal shifting lever arranged underneath the key levers F and engaging at-its rear end with a depending 5& formed on the lower side of the carriage H and attached near its front end by vertical pivot bolt to the lower side of the front frame a of the machine.

72, represents a-coiled spring attached at one end to the shifting lever H and at its 7; opposite end to the front frame a; of the machine. A vertical movement is imparted to the carriage frame and the carriage I-I supported thereon by depressing the key levers. The carriage'ismoved transversely from right to left by the shifting lever H and spring h.

The shifting lever H is composed of two sections it 71. which are connected by a hinged joint h so as to allow the inner arm k of the lever to take part in the vertical movement of the carriage. The outer arm k is provided at its free end with a thumb piece hwhereby the carriage can be moved transversely to the right-hand side of the machine. If desired the shifting lever may be constructed of a single piece of spring metal having suificient elasticity to permit the upward movement of the carriage.

I represents a T-shaped pawl or detent pivoted in an opening in the upper portion of the carriage H and adapted to engage with its rear leg 71 against oneof a series of stops 2" arranged on a transverse bar 71 and with its front leg i against one of a series of teeth 2' formed on the upper side of the cross bar 9 of the carriage frame as shown in Figs. 3 and 5. The rear leg of the pawl I engages against one of the stops 5 when the carriage is in its lowestposition as shown in Figs. 3, 4 and 5, and the front leg 23 of the pawl engages with a tooth 2' of the cross bar 9, when the carriage is raised and its rear leg disengaged from the stop a".

The stops 2" are provided with backwardly inclined top faces and the teeth 71 on the cross bar g are arranged slightly in.

from the stop i, by the upward movement of the carriage and will engage immediately against the next tooth i on the bar g and hold the carriage against further transverse movement to the left while the key lever is depressed. Upon releasing the key lever the carriage descends and the leg 6 of thepawl I during the downward movement of the carriage strikes against the inclined face of the stop 2" below thepawl, whereby the downward movement of the pawl is arrested until the pawl is released from the tooth i When the pawl has been released from the tooth 2' the carriage is permitted to be moved to the left by the shifting lever H until the pawl engages .tinglyfrom one stop to another. lhe car-' rlage is returned to its point of beginning by the operator swinging the lever H on its pivot by means of the thumb piece h. The transverse loar 2' is movably secured to two laterally projecting ears 7'' on the frames A A by screws 3' These screws pass through elongated openings 7' Figs. 4 and 5 in the bar 2' and are secured to the ears y" represents a dog or catch which engages with a nose j on the bar 2' and whereby the latter is held in a locked position. j represents a spring whereby the bar 71 is moved to the left when released from said catch j. When the bar 71 is released from the catch j and moved to the left by the spring 7' the stops 2" will be arranged in rear of the teeth '5 so that the pawl I will clear the stops 2" when the carriage descends, and will not be released from the teeth on the bar 9 of the carriage frame. In this position of the bar 2' the carriage is held from moving transversely upon depressing and releasing a key lever by the pawl I remaining engaged with one of the teeth 2' on the bar 9 of the carriage frame.

I represents a space bar arranged in rear of the shifting bar 2' and secured at its opposite ends to vertical guide rods i, which are guided at their lower ends in lugs secured to the side frames. The upper ends of these guide rods are attached to the inner ends of rock levers 2" which latter are secured at their outer ends to a transverse rock shaft i mounted in bearings secured to the rear of the machine. I rep resents a space lever arranged above the key levers F and pivoted to the side frame A. The spacelever I is connected with the rock shaft i by a longitudinal rod i secured to the short arm of thespace lever,

secured f'to the rock face of one of the teeth on the space bar.

Upon depressing the space lever 1 the space bar I is raised and carries with it the pawl I of the carriage H, until the pawl is re- 20 leased from the stop z" when the shifting lever H will cause the carriage to move to the left until the pawl I strikes against the front vertical side of the next adjacent tooth i on the spacebar 1: Upon releasing the space lever I the space bar I is allowed to descend, which movement releases the pawl I and the carriage H, and permits the pawl to engage against the next stop 5. When. the stop bar 2' has been moved to the left so that the pawl engages against, the teeth a" of the bar g as before described, and it is desired to shift the'carriage, the'space lever I is depressed and the space bar I raised so as to disengage the pawl I from the tooth 85 i of the bar g, when the carria e is moved to the left by the shifting bar as before and the pawl I engages againstthe next' tooth it upon releasing the space lever.

J Figs. 1, 2, 3 and 4 represents a series of forwardly inclined spring levers arranged side by side, on the rear side of the machine. These spring levers are preferably secured at their lower ends to blocks or sleeves k which are mounted upon a cross bar 70 arranged above the space bar I. Each sleeve it carries a spring lever J and is provided with a. forwardly and downwardly curved finger k The finger 70 of each sprmg lever J projects over thepath of the carriage H, so that the latter will stand below said fingers as it is moved from one stop 71 to another. As the carriage is raised upon depressing a key lever the finger k immediately above the carriage will be raised and its spring lever J deflected or swung backwardly; The spring levers J bear with their upper ends against the upper cross bar w of the frame of the machine when at rest.

J represent-s a series of pawl arms mounted-on the shaft 1) and each provided at its outerend with a pawl J The pawl arm's J are each arranged adjacent to the cam disk of each registering wheel B as shown in Figs. 1, 3, 6, and. so that its pawl J engages with a tooth on the adjacent wheel B. The hub is? of each pawl arin J is preferably made hollow as shown in Figs. 6 and 7, so as to form a. casing for a coiled return spring is which surrounds the J, so that when the lever is swung backwardly it causes the pawl armto move downwardly and turn the registering wheel B in the direction of the arrow in Figs. 3 and 6. The pawl arm J and its spring lever J are returned to their normal position by the spring is after each forward stroke of the pawl arm,

'L-Figs. 1, 3, and 6 represents a fixed transverse stop bar secured at opposite ends to the inner sides of the disks C. The backward stroke of each pawl arm J is arrested by a nose I formed on the arm J, striking against the stop bar L.

m Figs. 1, 3 and 6 represents a series of transversely movable stop bars arranged radially around the peripheries of the registering wheels with their ends projecting through radial grooves m formed in the end disks G. The ends of the stop bars m project through openings m formed in the end frames A A as shown in Figs. 4 and 6 whereby they are held against radial displacementin' the disks C. The stop bars m increase in value in the direction of the arrow m in Fig. 3, and are numbered so as to embrace the units 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9, and also all the products of any two as l'0'12 etc., there being thirty-seven stop bars which embrace all the units as well as the entire unit multiplication system, as shown in Fig. 3.

As shownin Figs. 1, 3, 4, and 6 each stop bar m is provided on its inner edge opposite the path of the pawl arms J with recesses or notches m so as to allow the pawl arms J to move freely past the same, when the stop bars are in their normal position as shown in the above figures of the drawings,

and with-projecting portions wa arranged between each. two adjacent notches or recesses m whereby the movement of the pawl arms J is arrested when the stop bars are moved in the path of the pawl arms. When a stop bar intercepts a pawl arm the latter a secured to the side frame A of the machine. The opposite end of each stop bar m is provided with a coiled spring 10 which surrounds a, finger a formed on the end of the bar on. The springs a are connected at their outer ends to-said fingers and bear with their inner ends against the side frame A, whereby the stop bars m are held 1n the1r normal position, with their recesses m in the path of the pawl arms J.

As shown in Figs. 6 and provided with a tooth a having an abrupt front or actuating face and an inclined or retreating back, and is held in engagement with the teeth of the registering wheel by a suitable spring a. The outer face a of the pawl J 2 is arranged close to the inner longitudinal edge of the projecting ,portlons at of the stop bars m, so that when one of sa d stop bars is moved across the ath of said pawl, to arrest the movement of the arm J, the pawl J 2 will be held against the tooth of the wheel B with which it is in engagement, by the projecting portion on. The stop bar we bears against the outer side of sand pawl and locks the wheel B against rotation. The pawl in this manner will be held against forward or backward movement until the stop bar m has again returned to its normal position, with one of its notches m opposite the pawl J when the latter is released and returned to its normal position by the spring 7%.

P represents a serles of transversely movable slides arranged side by side, one in rear of the other as shown in Figs. 1, 2, and 3. These slides are preferably arranged obliquely. The ends 79 of the slides Pare rectangular and are arranged in openings formed in the side frames A A. p are shoulders formed near the opposite ends of the slides P, and adapted to bear against the side frames A A whereby the movement of the slides P is limited in either direction. Each slide P is provided at its end adjacent to the side frame A with a key or thumb piece which is numbered to correspond with the number of a key lever'as shown in Figs. 2 and 4:, and with'a spring 79 whereby the slides P are moved outwardly when released.

P represents a rock shaft mounted in brackets p. The rock shaft P is arranged above the outer ends of the slides vP and is provided with a series of laterally projecting catches 39 one for each slide P.- These catches p bear with their lower inclined faces upon .the top of the slides P and en gage with a spur or nose 3;, formed on the top of each slide, when said slides are moved inwardly. These spurs p have inclined front faces and abrupt backs so that upon moving the slide P inwardly the catches p and the rock shaft P are swung upwardly 5 until the catch above the slide P drops back 7, each pawl J is construction prevents the possibility of more than one slide P being held in an innermost or locked position .at one time. The catches p are held in a locked position by a spring p secured to one end of the rock shaft P.

Each slide P is provided with a row of vertical pins B, there being nine of said pins for each slide. The pins R- move in vertical openings arranged in top and bottom flanges r 1' formed in each slide P and are held in an elevated position by springs 1 which surround the plus B and are interposed between the lower flange 1" and transverse pins 1' secured in the upper portion of each pin R. The pins r also serve to limit the upward movement of the pins R. The pins R on each slide P increase in value from left to right. As for example: In the first slide P No. 1 its pins represent in value from one to 9, the first pin to the left being 1 and the last pin to the right 9. The pins on slide P No.

. 2 begin with the value of 2, and this number is added to itself eight times successively so that the value of the last pin on this slide is 18. The pins on slide P No. 3 begin with the value of 8 and this number is added to itself on each succeeding pin in the same manner as on slide No. 2 so that the value of its last pin represents 27. The pins of each of the succeeding slides Nos. 4, 5,- 6, 7, 8, and 9 begin at the left with the value of 4, 5, 6, 7, 8, and 9 respectively, and the re maining pins of these slides increase in value in the same manner by adding the number of the first pin to itself eight times successively. As clearly shown in Fig. 2 the numbers on the pins R increase from the front to the rear of the machine in the same manner as they increase from left to right of themachine on each slide P.

- S represents nine narrow horizontal open wings or swinging frames arranged side by side as shown in Figs. 2, and 4, and pivoted lengthwise of the machine in the upper portion of two oblique bars or frames S S by pivots 8. Each wing S is connected at oppo- 'site ends in front of its pivots sby vertical s s and bearing with their upper ends against. the lower sides of the projecting ends of the wings S, and with their lower R, there being one elbow lever for each pin ends against the upper side of a flange formed on the lower end of each frame S Each wing S consists of a bar a, a. second bar parallel therewith, and a pair of relatively short bars which connect the bar 8 with the second bar, forming a longitudinal opening '8 through each wing-plate S, see Figs 2 and 4. When the slides P are in their normal or forward position the pins R will be arranged below the open portion a of the wings. 'When a slide has been .moved inwardly and is locked by its catch p the pinsR attached to this slide will stand immediately below the longitudinal bars 8 of the wings, so that upon depressing any one of the wings by means of its "key lever the in R below the bar 8' of this wing will also be depressed.

As represented in Figs. 1, 3, and 4, T represents elbow levers arranged below the pins R. These levers are arranged side by-side upon longitudinal bars at secured at opposite ends to the lower portlon of the oblique frames S S The upper arm of each elbow lever T is provided with a flat bearing face 6 and the lower long arm t? of each elbow lever is connected by a rod or wire F, with the lower end of one of the vertical levers N, which is connected as before described with a movable stop'barm. The pins R correspond in value with the stop bars m and each pin R having a given Value is connected by means of its lever T, rod t andleveFN vfiui'a'sufi) bar 'irrhaving the same value, so that upon depressing a pin R by a wing S, and key lever F the stop bar on corresponding in value with the depressed pin will be actuated by the lever T,

rod and leverN connected therewith.

I As shown in Fig. 4 the upperend of each elbow lever T is arranged a slight distance in advance of the lower projecting ends of the pins R. when the slides P are in their normal or .forward position, but will stand immediately below the pins R of a slide that has been moved inwardly and locked by its catch 72*". Upon depressing a key lever when a slide is in this last mentioned position the bar 8 of the wing S attached to said key lever, will swing downwardly and depress the pin R below the same, and the pin R in turn will move the lever T so that the lower arm t of the same will swing backwardly toward the left hand side of "the machine, Fig. 4.

This movement of the lever T, causes the le-.

ver N connected therewith to swing on its pivot a and move outwardly to the right a stop bar m corresponding in value -tothe depressed pin R. This outward movement of the stop-bar m allows the registering wheel to move a number of teeth correspond- I ing with the value of the depressed pin R as above described. When the key lever F is released the stop bar m and. the levers N and T are returned to their normal position by the spring a of the stop bar m, and the wing S and the pin R are again elevated by Y their depending ends with hooks to which en-' gage under noses or hooks u secured to the adj acent side frames A A, when the carriage frame G is in' its lowermost position. a is a cross bar arranged a short distance below the key levers Fan-Q secured at its ends to the horizontal'arms a of each lever U. u represents a spring whereby each lever U is held in engagement with the nose u. The upward movement of the rod 10 is limited by a stop pin a ,The lever U serves to lock the carriage frame in a, depressed position and hold the same against vertical movement.

It will be observed that the first part of the downward movement of a key.lever F tends to move its wing S, the pin R arranged below the same, the bell crank T, lever N and stop m as above described, the cross bar 9 acting as a fulcrum for the key lever. As this downward movement of the key lever continues, its lower side strikes the upper sideof the cross bar a and releases the hook u from the nose or projection u. During the balance of the-downward stroke of the key lever F its point of fulcrum is transferred to the pivot ofsthe equalizing bar a and the rear end of the carriage frame strike against one of .the curved fingers k of a spring arm J, and swing the latter back-- wardly. This movement of the spring arm causes the pawl arm J and the wheel B with which it is in engagement to rotate until the nose I of the pawl arm strikes against the shifted stop bar m. Upon releasing the key lever F the stop m is re turned to its normal position, thereby leasing the pawl arm J and lever J. The pawl arm J and lever J are returned to their normal position by the spring is"; the

carriage, by gravity; the key lever F, by the by their springs as above described. 'The distance of the upward movement of the I spring 7, and the wings and connections carriage H and thelower inner ends k of the springs bars J is the same at each upward stroke, while thebackward movement ofthe upper end of the spring bars J varies according tovthe distance of the movement of the registering wheel B with which its pawl arm J is in engagement. This difference of movement is compensated for, by the elasticity of'the spring bars J.

W represents the zero key lever arranged at the extreme left of the machine. The rear end of this key lever rests against the bar 9 of the carriage frame, and is supported near its center by a'rod w secured to the inner end of a rock lever w. The latter is secured to one end of a rock shaft @12 which is supported in bearings secured to the outer side of the side frame A. w is an outwardly projecting arm secured to the rear end of the rock shaft w and w is a lifting bar pivoted. at its upper end. to the arm w The lower end of the lifting bar w" is attached to the stop bar 2' by a screw engaging n an elongated opening w formed in the l ftlng bar. The lower end of the lifting bar 1s providedwith a lip or projection 21: which engages against the lower side of a nose to formed on the space bar I when the stop bar 5 is in an inward or locked position, where- 'by the space bar is raised upon depressing the zero lever W. v The lower end of the lifting bar wis disengaged from the space bar I when the stop bar 2' is moved outwardly, which permits the zero key ,to be depressed without imparting any movement to the space bar.

' The zero lever W is raised or bent upwardly above the cross bar a so that the zero lever will not come in contact with this cross bar and unlock the carriage'f-ram'e when this lever is depressed. I

w represents a rock shaft arranged transversely above the rear end of the carriage frame G and jeurnaiedatits ends in openings in the side frames A A. w represents forwardly projecting arms secured to op posite ends of the rock shaft-w and con-' nected with the rear ends of the side frames G of the carriage frame-G, by vertical links 102. By connecting opposite ends of the carriage frame in this manner, the carnage frame is held against tipping or twisting as both sides are caused to rise and descend simultaneously, and enables a .very light frame to be used. Any, suitable means may be employed for. resetting the numeral wheels to zero. The bar V is shown in the drawings in its lowermost position.

Each of the key levers F marked 1, 2,

3 4, 5, 6, 7 8, and 9, has arranged near the lower margin of its key a complemental number of smaller size, the two nufiibers on each key being the complement often.

W represents an indicating finger secured to the front portion of the carriage shifting lever H and which registers with a graduated segment W secured to the-flower front portion of t e frame of the machine and which indicates the location orposition of the carriage with reference to the spring levers J The operation of my improved calculat-, ing machine is as follows :-'-For instance, it is desired to add the two numbers 140 and .zero and shifted the bar H so that the carriage rests immediately below the spring lever J connected with the units wheel; the slide 1 No. 1 is moved to a locked position and the stop bar 2' locked in an inward position.

The zero key lever is first depressed. This does not move or change the units dial, but permits the carriage to move to the next spring lever J which is connected with the tens wheel B. The key lever 24 is then depressed causing the tens wheel B to move four teeth and the tens dial to indicate 4:. Upon releasing the key lever 4, the carriage will move and come to rest below the spring lever connected with the one hundreds wheel. pressed whereby the hundreds wheel will be moved a distance of one tooth, and indicate one on its dial. The dials now indicate 140. The carriage H is again returned to the units lever J and the key levers 0, 8, and 1 depressed successively, as in the case of the first number. Having depressed the key lever '8, the tens wheel moves a distance of eight teeth in addition to the four teeth already registered, so that the tens dial indicates 2. By this movement of the tens wheel past zero its cam and carrying mechanisln' ferred toadd various columns up or down instead of registering the sums from right -to left in succession as just described, the

catch j is swung upwardly so as to allow the bar 71 to move outwardly, which will prevent the carriage from feeding automatically from one spring lever J to the next and also disconnects the zero lever from the space bar I. 'The slide P No. 1 having been allowed to remain in a locked position, the key levers corresponding to the numbers in the units column are depressed in succession so as to register these numbers on the d als.

I is then depressed so as to raise the space bar I and allow the carriage to move to the next tooth or stop and beneath the lever J connected with the tens wheel.

ures of the tens column are then struck off umnv are registered when the operation is completed, and the sum of all the columns will be indicated on thevarious dials.

by its spring The space key gen the key levers 1n the same manner as in "the operation of the units colunm. In this manner .the figuresof each succeeding colthe carriage is returned so as to rest below the spring lever J of the units wheel, and the stop bar 71 is locked, so as to allow the carriage to automatically feed from one lever J to the next. The operator now moves the slide-P No. 5 inwardly, 5 being the st figure of the multiplicand, to a locked p0 tion and thereby automatically releases the-v .slide P No.1 which was in a locked plgsltion. This inward movement of the shde leverJ of the units wheel to turn the latter a distance of 10 teeth, therebyregistering zero on the. units. wheel and 1 on the tens wheel. The key lever 6 is next'depres'sed causing its wing S to depress pin No.

and move stop bar m No. 30 across thepath of the pawl arm of the tens wheel, and the lever J of the tens wheel to move the latter a distance of thirty teeth in addition to the one already registered. This movement of the tens wheel causes the hundreds wheel to move a distance of three teeth sothat the dials will now indicate 310 which is the product of 62 multiplied by 5. The operator now returns the carriage H to the units spring bar J and moves the slide P No. 3, corresponding to the second figure of the ,multiplicand, into a locked position thereby releasing slide P No. 5. This arranges all the pins R of the slide P No. 3 below the various'actuating bars 8" of the wings S.

The operator now depresses the space key I so that the next figure will stand in the tens column, or rather be registered on the tens wheel. The key lever No. 2 is then depressed which causes the pin R No. 6 to be depressed, so as to move the stop bar m- No. 6 and the spring arm J to turn the tens wheel a distance of six teeth, so that the dial of this wheel will indicate 7. The operator now depresses key lever No. 6 which causes pinR No. 18 to bedepressed and move the stop bar m No. 18 into the path of the pawl arm of the hundreds wheel, and the spring lever J to move this wheel a.. distance of eighteen teeth in addition to" the three registered. This movement of the hundreds wheel'causes its dial to indicate 1 and the dial of the thousands wheel to indicate 2,

, the latter having been moved two teeth by the camarm of the hundreds wheel. The four dials will now indicate the product 2170. I
